Description

Knowledge Representation (KR) on the Web has been a topic for Semantic Web research for a while and is increasingly relevant for practitioners – e.g., in the Open Data Movements or for Research Data Management. The standard for KR on the Web has been OWL for 10 years., in which numerous experiences has been gained. These experiences has prompted us to propose an approach aiming to augment and complement OWL based on prototypical objects. Prototypes have been explored in early Frame Representation Systems, but have been largely neglected in the last decades. In my talk I present a syntax and a formal semantics for prototype representation systems, proving that also Prototypes Systems can provide a formal underpinning for Knowledge Representation. Initial performance results will also be presented and are encouraging.
Finally I will conclude with prospects and open research challenges.
